GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(165, 812) = 133980
GCD(165, 812) = ( 165 x 812 ) / 133980
= 165 / 812
= 165
Step2:
LCM(1, 883) = 883
GCD(1, 883) = ( 1 x 883 ) / 883
= 1 / 883
= 1
Step3:
LCM(1, 561) = 561
GCD(1, 561) = ( 1 x 561 ) / 561
= 1 / 561
= 1
So, Greatest Common Divisor of 165, 812, 883, 561 is 1
